Several North Texas hospitals are now participating in an experimental COVID-19 coronavirus treatment.

Some patients who have recovered are donating their plasma, which will be given to other coronavirus patients who are still sick. There's a strict vetting process for people who are involved.

The experimental treatment got underway last weekend on a patient on a ventilator at Texas Health Fort Worth. Officials say they are monitoring to see if the person improves.

“For somebody to be a COVID antibody donor he or she has to have been tested negative two occasions by the hospital that they are now negative for that infection. Then that person is identified as a candidate donor for therapeutic antibodies,” said Merlyn Sayers, CEO, Carter BloodCare.
